Detailed Description

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

First, an example of the structure of the beverage supplying apparatus 100 according to the embodiment of the present invention will be described with reference to fig. 1 to 3. Fig. 1 is a front view of a beverage supplying apparatus 100 according to an embodiment of the present invention. Fig. 2 is a front view showing the inside of the beverage supplying apparatus 100 according to the embodiment of the present invention when the front cover door is opened. Fig. 3 is a diagram showing an external configuration of the beverage supplying apparatus 100 according to the embodiment of the present invention.

As shown in fig. 1, the beverage supply apparatus 100 includes a touch panel 2 on an openable and closable front cover door 1. The touch panel 2 is an operation accepting unit that displays a beverage option to the user of the beverage supply apparatus 100 and accepts a beverage selection operation by the user.

Specifically, the touch panel 2 displays an option of diluting a main raw liquid constituting a main beverage with carbonated water and an option of adding an ingredient raw liquid to the main beverage as a flavor, and accepts an operation of selecting the main raw liquid and the ingredient raw liquid from a user.

As shown in fig. 1, physical buttons 3a to 3c are provided below the touch panel 2. The physical buttons 3a to 3c receive an operation for instructing the ejection of the beverage from the user. Further, container placement positions 4a to 4c on which a user places a container (a glass, a cup, or the like) are provided below the physical buttons 3a to 3c, respectively.

The physical button 3a corresponds to the container placement 4a, and corresponds to the dilution water nozzle 5a and the stock solution nozzle 50 shown in fig. 2. The physical button 3b corresponds to the container placement site 4b and corresponds to the nozzle 5b shown in fig. 2. The physical button 3c corresponds to the container placement site 4c, and corresponds to the dilution water nozzle 5c, the stock solution nozzle 51, and the carbonated water nozzle 52 shown in fig. 2.

After the user selects a beverage on the touch panel 2, the user places the container in any one of the container placement positions 4a to 4c and presses any one of the physical buttons 3a to 3 c.

For example, when the physical button 3a is pressed, the raw liquid in the bag-in-box (hereinafter referred to as BIB)6 shown in fig. 2 is discharged from the raw liquid nozzle 50 as a discharge flow by the operation of the catheter pump 17 for BIB. The jet flow of the raw liquid collides with the jet flow of the dilution water (tap water) jetted from the dilution water nozzle 5a and is mixed. Thereby, a beverage is produced. The beverage thus produced is supplied to a container placed at the container placement site 4 a.

For example, when the physical button 3b is pressed, the undiluted liquid and the diluted water and/or the carbonated water are mixed in the nozzle 5b, and a beverage is produced. The beverage thus produced is ejected from the nozzle 5b and supplied into the container placed at the container placement site 4 b.

For example, when the physical button 3c is pressed, the raw liquid in the BIB7 shown in fig. 2 is ejected from the raw liquid nozzle 51 by the operation of the catheter pump for BIB 18 to form an ejection flow. The jet flow of the raw liquid collides with and is mixed with the jet flow of the dilution water jetted from the dilution water nozzle 5c and/or the jet flow of the carbonated water jetted from the carbonated water nozzle 52. Thereby, a beverage is produced. The beverage thus produced is supplied to the container placed at the container placement 4 c.

Further, while the physical buttons 3a to 3c are pressed, the above-described beverages are supplied to the container.

The drive of the BIB catheter pumps 17 and 18 is controlled by a control unit 20 (see fig. 4) described later. The control unit 20 reads setting data for controlling the drive of the BIB catheter pumps 17, 18 from a storage unit 21 (see fig. 4) described later, and controls the drive of the BIB catheter pumps 17, 18 based on the setting data. Thus, the stock solution was carried out from the interior of BIB6 and BIB 7.

The carbonated water nozzle 52 may be provided on the BIB6 side, or may be provided on both the BIB6 side and the BIB7 side.

The

BIBs

6 and 7 are disposed in the refrigeration area. Stock solutions to be stored under refrigeration are stored in the BIB6 and BIB 7. Further, a stock solution that does not need to be refrigerated is stored in the stock solution tank 10 described later with reference to fig. 3.

Here, the stock solution in the present embodiment includes not only a concentrated solution containing sugar but also a concentrated solution containing no sugar (for example, stock solutions of green tea, black tea, and the like).

The nozzle 5b is a mixing section for mixing water or carbonated water with a main raw liquid at a predetermined ratio to produce a main beverage, and mixing the ingredient raw liquid in an undiluted state with the main beverage to produce a beverage (hereinafter referred to as flavor-added beverage). The flavor-supplemented beverage produced by the nozzle 5b is discharged from the nozzle 5b into the container placed on the container placement site 4 b.

Thus, by mixing the main stock solution and the ingredient stock solution together, the options of the taste of the beverage provided to the user can be greatly increased.

Here, the main stock solution and the ingredient stock solutions are stored in a stock solution tank 10 shown in fig. 3 to be described later. The nozzle 5b discharges only water or only carbonated water in addition to the flavor-supplemented beverage.

As shown in fig. 3, the beverage supplying apparatus 100 includes: a purification filter 8, a carbon dioxide storage tank 9, and a plurality of raw liquid tanks 10.

The purification filter 8 purifies tap water supplied from the woven tube 11 and supplies the purified water to the inside of the beverage supply apparatus 100 through the woven tube 12. The braided tube 12 is connected to, for example, a dilution water inlet solenoid valve 31 (see fig. 4 and 8 described later) provided inside the beverage supplying apparatus 100. Also, purified water supplied to the inside of the beverage supplying apparatus 100 is directly supplied to a user as a beverage, or is used as dilution water or pressurized water.

Carbon dioxide is stored in the carbon dioxide storage tank 9. The carbon dioxide is supplied to the carbonator 23 through the braided tube 14 at a prescribed pressure (for example, 0.6MPa) set in the gas regulator 13. The carbon dioxide is supplied to each raw liquid tank 10 through a braided tube 15 at a predetermined pressure (for example, 0.2MPa) set in a gas regulator 13.

The plurality of raw liquid tanks 10 store different raw liquids, respectively. These stock solutions are used as either the main stock solution or the ingredient stock solution, as described above. These raw liquids are pressed out by the pressure of the gas supplied from the carbon dioxide storage tank 9, and supplied to the nozzle 5b through the braided tube 16.

Next, a control process of beverage supply in the beverage supply device 100 according to the present embodiment will be described with reference to fig. 4 and 5. Fig. 4 is a diagram showing a piping system of the beverage supplying apparatus 100 according to the embodiment of the present invention. Fig. 5 is a timing chart of the beverage supply apparatus 100 according to the embodiment of the present invention when supplying a beverage.

(method of supplying flavor-supplemented beverage with Strong Carbonic acid)

First, an example of the control operation when supplying a strongly carbonated flavor-supplemented beverage will be described.

Here, the strongly carbonated flavor-supplemented beverage is a beverage obtained by mixing a main raw liquid, carbonated water, and an ingredient raw liquid.

As shown in fig. 4, the beverage supplying apparatus 100 includes, in addition to the touch panel 2, the physical buttons 3b, and the nozzle 5b, the following: the raw liquid tanks 10a and 10b, the control unit 20, the storage unit 21, the carbonated water solenoid valve 22, the carbonator 23, the

flow meters

24 and 40, the first raw liquid solenoid valve 25, the first raw liquid motor 26, the first raw liquid pump 27, the second raw liquid solenoid valve 28, the second raw liquid motor 29, the second raw liquid pump 30, the diluting water inlet solenoid valve 31, the diluting water solenoid valve 32, the diluting water pump motor 33, the diluting water pump 34, and the pressurized water solenoid valve 39.

The raw liquid tank 10a, the raw liquid tank 10b are each one of the raw liquid tanks 10 of fig. 3, and store a raw liquid (e.g., a cola raw liquid, an orange raw liquid, etc.) serving as a main raw liquid or an ingredient raw liquid.

The control Unit 20 is a control device such as a CPU (Central Processing Unit). The storage unit 21 is a Memory device such as a ROM (Read Only Memory) or a RAM (Random Access Memory).

When the user performs an operation of selecting a strongly carbonated flavor-added beverage on the touch panel 2, the control unit 20 reads data on the selected beverage from the storage unit 21.

The data is, for example, data of dilution ratios of the master stock solution, carbonated water, and ingredient stock solutions registered in correspondence with a combination of the master stock solution and the ingredient stock solutions; setting data for controlling the opening and closing of the solenoid valves (carbonated water solenoid valve 22, first stock solution solenoid valve 25, second stock solution solenoid valve 28, dilution water inlet solenoid valve 31, dilution water solenoid valve 32, pressurized water solenoid valve 39) according to the dilution ratio; and setting data for controlling the driving of the motors (the first stock solution motor 26 and the second stock solution motor 29) based on the dilution ratio.

When the user presses the physical button 3b, the control unit 20 performs the following control based on the above data.

First, as shown in fig. 5, when the physical button 3b is pressed, the control unit 20 turns on the carbonated water solenoid valve 22. Thus, the carbonated water produced by carbonator 23 is sent to nozzle 5b through carbonated water solenoid valve 22 and flow meter 24 which are in an open state.

Further, the amount of carbonated water produced by carbonator 23 is managed using a level switch provided at carbonator 23. If the amount of carbonic acid water stored in the carbonator 23 is less than the predetermined amount, the level switch is turned on. When the liquid level switch is turned on, the controller 20 performs the following control to produce carbonated water.

That is, the control unit 20 drives the dilution water pump motor 33 by opening the dilution water inlet solenoid valve 31 and the pressurized water solenoid valve 39. At this time, the dilution water solenoid valve 32 is controlled to be in a closed state. Thereby, the dilution water pump 34 is driven to supply pressurized dilution water (pressurized tap water) to the carbonator 23 through the dilution water inlet solenoid valve 31 and the pressurized water solenoid valve 39.

The dilution water supplied to the carbonator 23 is mixed with carbon dioxide to be carbonated water. Thereafter, when the amount of the produced carbonic acid water reaches a predetermined amount, the liquid level switch is turned off. When the liquid level switch is turned off, the control unit 20 stops the control. Thereby, the production of carbonated water is stopped.

Here, the flow meter 24 generates a pulse each time a unit amount of carbonated water is passed. Then, the control unit 20 performs the following control, for example, based on the pulse.

The control unit 20 counts the pulses of the flow meter 24 to detect the flow rate of carbonated water delivered from the nozzle 5b while the physical button 3b is pressed.

The control unit 20 counts pulses of the flow meter 24, and controls the rotation speed of the first raw liquid motor 26 based on the pulses, thereby controlling the flow rate of the first raw liquid sent from the nozzle 5b while the physical button 3b is pressed.

The control unit 20 counts pulses of the flow meter 24 and controls the rotation speed of the second raw liquid motor 29 based on the pulses, thereby controlling the flow rate of the second raw liquid sent from the nozzle 5b while the physical button 3b is pressed.

The control unit 20 is also provided with a timer that operates simultaneously with the pressing of the physical button 3b and measures the elapsed time from the pressing time. Then, the control unit 20 performs the following respective controls, for example, based on the elapsed time measured by the timer.

As shown in fig. 5, after a predetermined time (for example, 0.2 second) has elapsed from the opening of the carbonated water solenoid valve 22, the control unit 20 controls the first stock solution solenoid valve 25 and the second stock solution solenoid valve 28 to open the first stock solution solenoid valve 25 and the second stock solution solenoid valve 28.

At the same time, as shown in fig. 5, the control unit 20 controls the first stock solution motor 26 to start driving of the first stock solution motor 26. The first raw liquid pump 27 sends the main raw liquid supplied from the raw liquid tank 10a to the nozzle 5b through the first raw liquid solenoid valve 25 in an open state by driving the first raw liquid motor 26. The first raw liquid pump 27 is a pump such as a gear pump.

After a predetermined time a (for example, 0 to 0.7 seconds) has elapsed from the start of driving the first stock solution motor 26 (the start of opening the first stock solution solenoid valve 25 and the second stock solution solenoid valve 28), the control unit 20 controls the second stock solution motor 29 to start driving the second stock solution motor 29.

At this time, the control unit 20 intermittently drives the second raw liquid motor 29. For example, as shown in fig. 5, the second dope motor 29 repeats the following cycle: the driving is performed for a predetermined time B (for example, 0.1 to 0.3 seconds) and the driving is stopped for a predetermined time C (for example, 0.7 to 0.9 seconds).

The second raw liquid pump 30 sends a small amount of undiluted ingredient raw liquid supplied from the raw liquid tank 10b to the nozzle 5b through the second raw liquid solenoid valve 28 in an open state by driving the second raw liquid motor 29. The second raw liquid pump 30 is a pump such as a gear pump.

As described above, while the physical button 3b is pressed, the carbonated water, the main raw liquid, and the ingredient raw liquid are mixed in the nozzle 5b, and the flavor-added beverage as strong carbonic acid is discharged into the container placed in the container placement site 4 b.

In addition, as described above, the beverage supplying apparatus 100 mixes the carbonated water and the stock solution of the main ingredient at a predetermined ratio to produce the main beverage, and mixes the stock solution of the ingredient in an undiluted state to the main beverage to produce the beverage, and the control unit 20 changes the predetermined ratio at the time of mixing the carbonated water and the stock solution of the main ingredient in accordance with the combination of the stock solution of the main ingredient and the stock solution of the ingredient.

This makes it possible to keep the sugar content of the beverage to be produced within a certain range regardless of the combination of the main stock solution and the ingredient stock solution.

Instead of the flow meter 24, the flow rate of carbonated water may be detected based on the open time (time of the on state) of the carbonated water solenoid valve 22. The flow rates of the first raw liquid and the second raw liquid may be detected by a flow meter (not shown) (for example, flow meters provided downstream of the first raw liquid solenoid valve 25 and downstream of the second raw liquid solenoid valve 28, respectively).

Further, not only the flow meter 24 may generate a pulse every time a unit amount of carbonated water is passed, but the control unit 20 may also measure the time by counting the pulse, and control the first stock solution motor 26, the second stock solution motor 29, the carbonated water solenoid valve 22, the first stock solution solenoid valve 25, the second stock solution solenoid valve 28, and the like based on the time.

Further, since the ingredient raw liquid is a raw liquid added as a flavor, the amount of addition is only a little, and if the amount is too much, the balance of the flavors of the main raw liquid and the ingredient raw liquid is lost. Therefore, it is necessary to accurately add a predetermined amount of the ingredient stock solution.

Similarly to the ejection control of the main raw liquid shown in fig. 5, if such a small amount of the ingredient raw liquid is added for a long time, it is difficult to control the ejection amount of the ingredient raw liquid.

Therefore, in the present embodiment, the ingredient stock solution is intermittently added in an undiluted state. Thus, the ingredient stock solution can be accurately added in a predetermined amount, and the taste balance can be prevented from being disturbed. As a result, the user can be provided with a beverage having a taste desired by the beverage manufacturer.

Further, as described above, when the ingredient raw liquid is fed by the second raw liquid pump 30, even a small amount of the ingredient raw liquid can be accurately added by a predetermined amount.

Thereafter, when the strongly carbonated flavor-supplemented beverage is discharged into the container and the physical button 3b is pressed, the control unit 20 closes the first raw liquid solenoid valve 25 and the second raw liquid solenoid valve 28, as shown in fig. 5.

At the same time, the control unit 20 stops the driving of the first stock solution motor 26 and the second stock solution motor 29. Thereby, the ejection of the beverage from the nozzle 5b is stopped.

After a predetermined time (for example, 0.1 second) has elapsed from the end of pressing the physical button 3b, the control unit 20 closes the carbonated water solenoid valve 22. The reason why the carbonated water solenoid valve 22 is not closed immediately after the pressing of the physical button 3b is completed is to wash the nozzle 5b with carbonated water.

As described above, according to the beverage supplying apparatus 100 of the present embodiment, the raw ingredient liquid is intermittently discharged in an undiluted state by using the raw ingredient liquid pump, so that the discharge amount of the raw ingredient liquid can be accurately controlled, and a beverage having a taste desired by a beverage manufacturer can be produced.

Next, a case where a cup adding operation of the beverage is further performed after the supply of the beverage will be described with reference to fig. 5. Fig. 5 shows a case where the physical button 3b is pressed for a time D as a cup continuation operation, and thereafter, the physical button 3b is further pressed for a time E.

As shown in fig. 5, the control unit 20 is configured not to drive the second raw liquid motor 29 when an elapsed time from the start of driving the first raw liquid motor 26 (or the start of opening the first and second raw liquid solenoid valves 25 and 28) is less than a predetermined time a (for example, 0 to 0.7 seconds) within a time D from the start to the end of pressing the physical button 3 b. At this time, no ingredient stock solution was added to the beverage of the next cup.

On the other hand, when the elapsed time from the start of driving of the first raw liquid motor 26 (or the start of opening of the first raw liquid solenoid valve 25 and the second raw liquid solenoid valve 28) is equal to or longer than a predetermined time a (for example, 0 to 0.7 seconds) within the time E from the start to the end of pressing the physical button 3b, the control unit 20 drives the second raw liquid motor 29. At this time, the ingredient stock solution is added to the beverage of the next cup.

By such control, the addition of the ingredient stock solution can be easily performed when the cup replacement operation is performed.

Further, in the case where the cup continuation operation in which the elapsed time from the start of driving of the first stock solution motor 26 is less than the above-described predetermined time a is repeated, the ratio of the ingredient stock solution in the beverage is low. Therefore, the control unit 20 may perform the following control.

Specifically, when the physical button 3b is pressed a plurality of times, the controller 20 may drive the second raw liquid motor 29 when the total of the elapsed times from the start of driving of the first raw liquid motor 26 (or the start of opening of the first raw liquid solenoid valve 25 and the second raw liquid solenoid valve 28) is equal to or longer than a predetermined time a (for example, 0 to 0.7 seconds).

Thus, even when the cup continuation operation is repeated in which the elapsed time from the start of driving of the first stock solution motor 26 is less than the predetermined time a, the ingredient stock solution can be added, and the beverage with the best taste can be served to the user.

(method of supplying flavor-supplemented beverage without Carbonic acid)

Next, an example of the control operation when supplying the carbonated flavor-free drink will be described. Similarly to the control operation at the time of supplying the strongly carbonated flavor-supplemented beverage described above, the control unit 20 can control the

solenoid valves

22, 25, 28, 31, and 32 and the

motors

26, 29, and 33 even when the non-carbonated flavor-supplemented beverage is supplied.

Here, the carbonated flavor-supplemented beverage is a beverage obtained by mixing a main stock solution, dilution water (tap water), and an ingredient stock solution.

Fig. 6A is a timing diagram of the supply of the flavor-supplemented beverage without carbonic acid. In the case of fig. 6A, even if the physical button 3b is pressed, the carbonated water solenoid valve 22 is not in an open state, and instead, the diluted water inlet solenoid valve 31 provided at the inlet of the water supply passage to the beverage supply device 100 is in an open state.

Further, the dilution water solenoid valve 32 is opened to drive the dilution water pump motor 33. Thereby, the dilution water pump 34 is driven to supply the dilution water to the nozzle 5b through the dilution water solenoid valve 32 and the flow meter 40 provided downstream thereof.

Here, the flow meter 40 generates a pulse every time a unit amount of dilution water is passed. Then, the control unit 20 performs the following control, for example, based on the pulse.

The control unit 20 counts the pulses of the flow meter 40, thereby detecting the flow rate of the dilution water sent from the nozzle 5b while the physical button 3b is pressed.

The control unit 20 counts pulses of the flow meter 40 and controls the rotation speed of the first raw liquid motor 26 based on the pulses, thereby controlling the flow rate of the first raw liquid fed from the nozzle 5b while the physical button 3b is pressed.

The control unit 20 counts the pulses of the flow meter 40 and controls the rotation speed of the second raw liquid motor 29 based on the counted pulses, thereby controlling the flow rate of the second raw liquid fed from the nozzle 5b while the physical button 3b is pressed.

At this time, the control unit 20 intermittently drives the second stock solution motor 29. For example, as shown in fig. 6A, the second dope motor 29 repeats the following cycle: the driving is performed for a predetermined time B (for example, 0.1 to 0.3 seconds) and the driving is stopped for a predetermined time C (for example, 0.7 to 0.9 seconds).

Thus, while the physical button 3b is pressed, the dilution water, the main stock solution, and the ingredient stock solution are mixed in the nozzle 5b, and the mixture is discharged as a carbonated flavor-added beverage into the container placed in the container placement site 4 b.

In addition, as described above, the beverage supplying apparatus 100 mixes the diluted water and the stock solution of the main ingredient at a predetermined ratio to produce the main beverage, and mixes the stock solution of the ingredient in an undiluted state to the main beverage to produce the beverage, and the control unit 20 changes the predetermined ratio at the time of mixing the diluted water and the stock solution of the main ingredient in accordance with the combination of the stock solution of the main ingredient and the stock solution of the ingredient.

Instead of the flow meter 40, the flow rate of the dilution water may be detected based on the open time (time of the open state) of the dilution water solenoid valve 32. The flow rates of the first raw liquid and the second raw liquid may be detected by a flow meter (not shown) (for example, flow meters provided downstream of the first raw liquid solenoid valve 25 and downstream of the second raw liquid solenoid valve 28, respectively).

In addition, the control unit 20 may be configured to measure the time by counting pulses generated by the flow meter 40 every time a unit amount of dilution water passes through the flow meter, and to control the first stock solution motor 26, the second stock solution motor 29, the dilution water electromagnetic valve 32, the first stock solution electromagnetic valve 25, the second stock solution electromagnetic valve 28, and the like based on the measured time.

Thereafter, when the carbonated flavor-supplemented beverage is discharged into the container and the physical button 3b is pressed, the control unit 20 closes the first raw liquid solenoid valve 25 and the second raw liquid solenoid valve 28 as shown in fig. 6A.

The control unit 20 turns on the carbonated water solenoid valve 22 for a predetermined time (for example, 0.1 second) from the end of pressing the physical button 3 b. The reason why the carbonated water solenoid valve 22 is turned on within the predetermined time after the physical button 3b is pressed is to wash the nozzle 5b with carbonated water.

The control unit 20 stops the dilution water pump motor 33 when the pressing of the physical button 3b is completed, closes the dilution water solenoid valve 32 after a predetermined time (for example, 0.2 second) has elapsed since the pressing of the physical button 3b is completed, and closes the dilution water inlet solenoid valve 31 after a predetermined time (for example, 0.5 second) has elapsed since the pressing of the physical button 3b is completed. The dilution water pump motor 33 is controlled in conjunction with the dilution water inlet solenoid valve 31 and the dilution water solenoid valve 32 to prevent the occurrence of water hammer.

Next, a case where a cup adding operation of the beverage is further performed after the supply of the beverage will be described with reference to fig. 6A. Fig. 6A shows a case where the physical button 3b is pressed for a time D as a cup continuation operation, and thereafter, the physical button 3b is further pressed for a time E.

As shown in fig. 6A, the control unit 20 is configured not to drive the second raw liquid motor 29 when an elapsed time from the start of driving of the first raw liquid motor 26 (or the start of opening of the first raw liquid solenoid valve 25 and the second raw liquid solenoid valve 28) is less than a predetermined time a (for example, 0 to 0.7 seconds) within a time D from the start to the end of pressing the physical button 3 b. At this time, no ingredient stock solution was added to the beverage of the next cup.

(method of supplying flavor-supplemented beverage with Weak Carbonic acid)

Next, an example of the control operation when supplying a weakly carbonated flavor-supplemented beverage will be described. Similarly to the control operation in the supply of the strongly carbonated or non-carbonated flavor-supplemented beverage described above, the control unit 20 can control the

solenoid valves

22, 25, 28, 31, 32, and 39 and the

motors

26, 29, and 33 even in the supply of the weakly carbonated flavor-supplemented beverage.

Here, the weakly carbonated flavor-supplemented beverage is a beverage obtained by mixing a main stock solution, diluted water (tap water), carbonated water, and an ingredient stock solution.

Fig. 6B is a timing chart when the weakly carbonated flavor-supplemented beverage is supplied. In the case of fig. 6B, different from the case of fig. 6A, when the physical button 3B is pressed, the dilution water inlet solenoid valve 31 is turned on, and the carbonated water solenoid valve 22 is intermittently turned on.

Here, the control unit 20 includes a timer that operates simultaneously with the pressing of the physical button 3b and measures the elapsed time from the pressing time. Then, the control unit 20 performs the following respective controls, for example, based on the elapsed time measured by the timer.

For example, as shown in fig. 6B, the controller 20 controls the opening and closing of the carbonated water solenoid valve 22 so that the carbonated water solenoid valve 22 repeats a cycle of 1.0 second to the open state and 1.0 second to the closed state. Thereby, carbonated water is intermittently supplied to the nozzle 5 b.

Here, the flow meter 24 generates a pulse each time a unit amount of carbonated water is passed. In addition, the flow meter 40 generates a pulse every time a unit amount of dilution water is passed. Based on these pulses, the control unit 20 performs the following control, for example.

The control unit 20 counts the pulses of the flow meter 24, and detects the flow rate of carbonated water delivered from the nozzle 5b while the physical button 3b is pressed.

The control unit 20 counts the pulses of the flow meter 40, and detects the flow rate of the dilution water sent from the nozzle 5b while the physical button 3b is pressed.

The control unit 20 counts pulses of the flow meter 24 or the flow meter 40, and controls the rotation speed of the first raw liquid motor 26 based on the pulses, thereby controlling the flow rate of the first raw liquid fed from the nozzle 5b while the physical button 3b is pressed.

The control unit 20 counts pulses generated by the flow meter 24 or the flow meter 40, and controls the rotation speed of the second raw liquid motor 29 based on the pulses, thereby controlling the flow rate of the second raw liquid fed from the nozzle 5b while the physical button 3b is pressed.

As shown in fig. 6B, the controller 20 opens the dilution water solenoid valve 32 while the carbonated water solenoid valve 22 is closed (for example, 1.0 second), and drives the dilution water pump motor 33 for a predetermined period of time (for example, 0.8 second) after the carbonated water solenoid valve 22 is closed. Thereby, the dilution water is intermittently supplied to the nozzle 5 b.

At this time, the control unit 20 intermittently drives the second stock solution motor 29. For example, as shown in fig. 6B, the second dope motor 29 repeats the following cycle: the driving is performed for a predetermined time B (for example, 0.1 to 0.3 seconds) and the driving is stopped for a predetermined time C (for example, 0.7 to 0.9 seconds).

In this way, while the physical button 3b is pressed, the carbonated water, the dilution water, the main stock solution, and the ingredient stock solution are mixed in the nozzle 5b, and the flavor-added beverage as weak carbonic acid is discharged into the container placed in the container placement site 4 b.

In addition, as described above, the beverage supplying apparatus 100 mixes the dilution water, the carbonated water, and the stock solution of the main ingredient at a predetermined ratio to produce the main beverage, and mixes the stock solution of the ingredient in an undiluted state to the main beverage to produce the beverage, and the control unit 20 changes the predetermined ratio at the time of mixing the dilution water, the carbonated water, and the stock solution of the main ingredient in accordance with the combination of the stock solution of the main ingredient and the stock solution of the ingredient.

Instead of the flow meter 24, the flow rate of carbonated water may be detected based on the open time (time of the on state) of the carbonated water solenoid valve 22. Instead of the flow meter 40, the flow rate of the dilution water may be detected from the open time (time of the open state) of the dilution water solenoid valve 32.

The flow rates of the first raw liquid and the second raw liquid may be detected by a flow meter (not shown) (for example, flow meters provided downstream of the first raw liquid solenoid valve 25, downstream of the second raw liquid solenoid valve 28, and the like).

Thereafter, when the weakly carbonated flavor-supplemented beverage is discharged into the container and the physical button 3B is pressed, the control unit 20 closes the first raw liquid solenoid valve 25 and the second raw liquid solenoid valve 28 as shown in fig. 6B.

Next, a case where a cup adding operation of the beverage is further performed after the supply of the beverage will be described with reference to fig. 6B. Fig. 6B shows a case where the physical button 3B is pressed for a time D as a cup continuation operation, and thereafter, the physical button 3B is further pressed for a time E.

As shown in fig. 6B, the control unit 20 is configured not to drive the second raw liquid motor 29 when an elapsed time from the start of driving the first raw liquid motor 26 (or the start of opening the first raw liquid solenoid valve 25 or the second raw liquid solenoid valve 28) is less than a predetermined time a (for example, 0 to 0.7 seconds) within a time D from the start to the end of pressing the physical button 3B. At this time, no ingredient stock solution was added to the beverage of the next cup.

While the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments and various modifications are possible. Hereinafter, such a modification will be described.

(modification 1)

In the above embodiment, only the ingredient raw liquid is intermittently discharged, but the main raw liquid may also be intermittently discharged. This will be described below with reference to fig. 7.

Fig. 7 is a diagram illustrating the intermittent discharge of the main raw liquid. Fig. 7(1) shows the driving timing of the first raw liquid motor 26 described in fig. 5, and fig. 7(2) shows the driving timing of the second raw liquid motor 29 described in fig. 5.

As shown in fig. 7, the first raw liquid motor 26 may be intermittently operated. Thereby, the main raw liquid is intermittently discharged to the nozzle 5 b.

At this time, the second stock solution motor 29 is driven in every other period among a plurality of periods in which the first stock solution motor 26 is driven. This enables the second raw-liquid pump 30 to be driven at a discharge amount smaller than that of the first raw-liquid pump 27. As a result, a small amount of undiluted stock solution of a predetermined amount can be accurately added.

Here, the second raw liquid motor 29 is driven in every other time slot, but the present invention is not limited to this, and the second raw liquid motor 29 may be driven in conjunction with each other at every N times (N is an integer of 1 or more) in a plurality of time slots in which the first raw liquid motor 26 is driven.

In this case, the undiluted ingredient stock solution and the main stock solution are discharged at the same time. This can further promote mixing of the carbonated water, the main raw liquid, and the ingredient raw liquid in the nozzle 5 b.

Further, by shortening the driving interval of the second stock solution motor 29 to some extent, a beverage in which carbonated water, the main stock solution, and the ingredient stock solution are uniformly mixed can be easily obtained whenever the user stops pressing the physical button 3 b.

In fig. 7, the timing at which the discharge of the ingredient raw liquid is started and the timing at which the discharge of the main raw liquid is started are set to be the same timing, but these timings may be different.

(modification 2)

In the modification 1, the intermittent discharge of the main raw liquid and the batch raw liquid is performed by the first raw liquid pump 27 and the second raw liquid pump 30, respectively, but the intermittent discharge may be performed by controlling the discharge of the pressurized main raw liquid and batch raw liquid by opening and closing the electromagnetic valves.

In this case, since the ingredient raw liquid is intermittently added in an undiluted state without continuously discharging the ingredient raw liquid for a long time, the ingredient raw liquid can be accurately added in a predetermined amount, and the taste balance can be prevented from being disturbed. As a result, the user can be provided with a beverage having a taste desired by the beverage manufacturer.

Next, a control process of beverage supply in the beverage supply device 110 according to the present modification will be described with reference to fig. 8. Fig. 8 is a diagram showing a piping system of the beverage supply device 110 according to the present modification. In fig. 8, the same reference numerals are used for the same components as those in fig. 4.

In the following, an example of a flavor-supplemented beverage (a beverage in which a main stock solution, carbonated water, and an ingredient stock solution are mixed) that supplies strong carbonic acid will be described.

As shown in fig. 8, the beverage supply device 110 includes, in addition to the touch panel 2, the physical button 3b, the nozzle 5b, the raw-material tanks 10a and 10b, the control unit 20, the storage unit 21, the carbonated water solenoid valve 22, the carbonator 23, the flow meter 24, the diluent water inlet solenoid valve 31, the diluent water pump motor 33, and the diluent water pump 34: a first stock solution electromagnetic valve 35, a first stock solution flowmeter 36, a second stock solution electromagnetic valve 37 and a second stock solution flowmeter 38.

The data is, for example, data of dilution ratios of the master stock solution, carbonated water, and ingredient stock solutions registered in correspondence with a combination of the master stock solution and the ingredient stock solutions; and setting data for controlling the opening and closing of the respective solenoid valves (the dilution water inlet solenoid valve 31, the carbonated water solenoid valve 22, the first stock solution solenoid valve 35, and the second stock solution solenoid valve 37) according to the dilution ratio.

First, as shown in fig. 9, when the physical button 3b is pressed, the control unit 20 turns on the carbonated water solenoid valve 22. The carbonated water produced by carbonator 23 is sent to nozzle 5b through carbonated water solenoid valve 22 and flow meter 24 which are in an open state. Since the method for producing carbonated water is as described above, the description thereof is omitted here.

Here, the flow meter 24 generates a pulse every time a unit amount of carbonated water passes through, and the control unit 20 counts the pulses. Since the control unit 20 performs processing based on the pulse as described above, description thereof is omitted here.

The control unit 20 includes a timer that operates simultaneously with the pressing of the physical button 3b and measures the elapsed time from the pressing time. Then, the control unit 20 performs the following respective controls, for example, based on the elapsed time measured by the timer.

As shown in fig. 9, the controller 20 controls the opening and closing of the first concentrate solenoid valve 35 and the second concentrate solenoid valve 37 after the carbonated water solenoid valve 22 is opened.

Specifically, after a predetermined time (for example, 0.2 second) has elapsed after the carbonated water solenoid valve 22 is opened, the control unit 20 intermittently opens the first stock solution solenoid valve 35 to discharge the main stock solution.

For example, as shown in fig. 9, the first raw liquid solenoid valve 35 repeats a cycle of an open state for a predetermined time and a closed state for a predetermined time. The supply amount of the main stock solution can be variably adjusted by the opening time of the first stock solution solenoid valve 35. Further, the supply amount of the main raw liquid may be adjusted by making the on time constant and making the cycle variable.

The control unit 20 also intermittently opens the second stock solution solenoid valve 37 to discharge the stock solution of the ingredient. For example, the second raw liquid solenoid valve 37 is turned on every other period of time among a plurality of periods of time in which the first raw liquid solenoid valve 35 is turned on.

This makes it possible to discharge the ingredient raw liquid at a discharge rate smaller than that of the main raw liquid. As a result, a small amount of undiluted stock solution of a predetermined amount can be accurately added.

Here, the second raw liquid solenoid valve 37 is set to be in the on state every other time period, but the present invention is not limited to this. For example, the second concentrate solenoid valve 37 may be set to the on state in an interlocking manner at every N (N is an integer equal to or greater than 1) times in a plurality of time periods in which the first concentrate solenoid valve 35 is set to the on state.

In addition, although the beverage supplying apparatus 110 mixes the carbonated water and the stock solution of the main ingredient at a predetermined ratio to produce the main beverage and mixes the stock solution of the ingredient in an undiluted state to the main beverage to produce the beverage as described above, the control unit 20 may change the predetermined ratio when mixing the carbonated water and the stock solution of the main ingredient according to a combination of the stock solution of the main ingredient and the stock solution of the ingredient.

Further, while the physical button 3b is pressed, the control unit 20 can appropriately detect the mixing ratio of the beverage during the manufacturing process based on the detected flow rates of the flow meter 24, the first raw liquid flow meter 36, and the second raw liquid flow meter 38.

Further, not only the flow meter 24 may generate a pulse every time a unit amount of carbonated water passes, the control unit 20 may measure a time by counting the pulse, and control the diluted water inlet solenoid valve 31, the diluted water pump motor 33, the carbonated water solenoid valve 22, the first stock solution solenoid valve 35, the second stock solution solenoid valve 37, and the like based on the time.

In the present modification, the controller 20 is configured to count the pulses generated by the flow meter 24, but may count the pulses generated every time a unit amount of raw liquid passes through either the first raw liquid flow meter 36 or the second raw liquid flow meter 38.

Thereafter, when the strongly carbonated flavor-supplemented beverage is discharged into the container and the physical button 3b is pressed, the control unit 20 closes the first raw liquid solenoid valve 35 and the second raw liquid solenoid valve 37, as shown in fig. 9. Thereby, the ejection of the beverage from the nozzle 5b is stopped.

After a predetermined time (for example, 0.1 second) has elapsed from the end of pressing the physical button 3b, the control unit 20 closes the carbonated water solenoid valve 22. The reason why the carbonated water solenoid valve 22 is not closed immediately after the physical button 3b is pressed is to wash the nozzle 5b with carbonated water.

As described above, according to the beverage supply apparatus 110 of the present modification, the amount of the ingredient raw liquid to be discharged can be controlled with high accuracy by intermittently discharging the ingredient raw liquid in an undiluted state using the electromagnetic valve, and a beverage having a taste desired by a beverage manufacturer can be produced.

Next, a case where a cup adding operation of the beverage is further performed after the supply of the beverage will be described with reference to fig. 9. Fig. 9 shows a case where the physical button 3b is pressed for time D as a cup continuation operation, and thereafter, the physical button 3b is further pressed for time E.

As shown in fig. 9, when the time period during which the first concentrate solenoid valve 35 is in the open state is less than two within the time D from the start to the end of the pressing of the physical button 3b, the control unit 20 keeps the second concentrate solenoid valve 37 in the closed state. At this time, no ingredient stock solution was added to the beverage of the next cup.

On the other hand, as shown in fig. 9, when the first concentrate solenoid valve 35 is in the on state for two periods of time during the time E from the start to the end of the pressing of the physical button 3b, the control unit 20 sets the second concentrate solenoid valve 37 to the on state for the second period of time during which the first concentrate solenoid valve 35 is in the on state. At this time, the ingredient stock solution is added to the beverage of the next cup.

Further, in the case where the cup continuation operation in which the first stock solution solenoid valve 35 is in the on state for less than two is repeated, the ratio of the ingredient stock solution in the beverage is low. Therefore, the control unit 20 may perform the following control.

Specifically, when the physical button 3b is pressed a plurality of times, if the total of the time periods during which the first concentrate solenoid valve 35 is opened at each time is two or more, the control unit 20 may open the second concentrate solenoid valve 37 at every other time period among these time periods.

Thus, even when the cup continuation operation is repeated for a time period in which the first stock solution solenoid valve 35 is in the open state of less than two, the ingredient stock solution can be added to supply the beverage with the best taste to the user.

Although the modified examples of the embodiment of the present invention have been described above, the modified examples may be implemented by arbitrarily combining the modified examples.
